Detailed Description

       A state machine for polygon selections.

       Pressing QwtEventPattern::MouseSelect1 or QwtEventPattern::KeySelect1 starts the selection
       and selects the first point, or appends a point. Pressing QwtEventPattern::MouseSelect2 or
       QwtEventPattern::KeySelect2 appends the last point and terminates the selection.
